I am about to change our dates from 11/14-11/21 to 10/31-11/7. Should I be concerned about crowds this week? This is our first trip so I will have nothing to compare it to but the crowd calendars put this week as busier than our original week. We are switching dates to stay at the Poly -- I will have 3 younger kids including a 4 month old so the space and location are tempting but I don't want to regret it because of crowds.
